Dexter filed an explosive sexual harassment lawsuit against her former lover Gregory Peters, who was her boss at Manhattan’s ritzy La Palestra gym, on November 12, 2013.

According to court documents obtained by Radar, Dexter interviewed for a job at the gym in May 2012, despite the fact that she had no valid personal trainer license. Peters “specifically hired [Dexter] because he was attracted to her, despite her lack of work experience,” the documents claim.

Peters “would ask [Dexter] to have sex with him on various pieces of equipment and training tables at La Palestra,” the complaint claims. “Even though the sexual relationship was consensual, [Dexter] still hesitated and/or protested having sex on the equipment,” but her boss “would convince [her] to have sex on the equipment because he was the manager and could make [Dexter] a great trainer.”

Then in early July 2013, the documents state, Peters “realized that this escalating affair could negatively affect his marriage and abruptly ended the relationship.”

Apparently, that sent Dexter into a tailspin.

“The end of the relationship and interactions [with Peters at work] continued to affect [Dexter emotionally and psychologically,” the complaint explains, “and as a result, in or around July 2012, [Dexter] was rushed to the Lenox Hill Hospital emergency room for severe panic attacks.”

Dexter asked bosses to make sure she wouldn’t interact with Peters at work, to no avail, the documents claim. In the meantime Peters allegedly “continued to repeatedly call [Dexter] and leave threatening and nasty messages, such as, ‘I wish I had never met you’ and ‘I regret the day that I ever hired you.'” He also told her to “Leave the company — resign already,” and “Become a stripper, that’s what you’re good at,” according to the complaint.

“But Defendant Peters would then also leave [Dexter] messages saying that his wife was away for the weekend and that he missed her,” the documents claim.

Cracking under the pressure, Dexter claims she “voluntarily checked herself into St. Luke’s Psychiatric Ward,” around September 1, 2012, where she was kept for roughly ten days.
